The roller I9 is a segment roller, so that as a circular is being fed the engaging part of the segment roller l9 will be at approximately its lowered position as shown in dotted lines in Fig. 4, and allowing the circular to be properly placed and positioned between the rollers when the segment roller i9 is rotated and is in the position shown in full lines in Fig. 4 whereby this segment roller will be in engagement or contact with the roller l l and the circular will be fed between the rollers I2 and 20. The folder arm I feeds the circular a sufficient distance into the rollers II and I9 to permit these rollers II and I9 to feed the circular between the rollers l2 and 20 after the blade has retracted. A stop pin 29, Fig. 1, carried by a part of the frame or structure I. is positioned below the arm l5 which carries, the, roller I l to prevent the springs H from urging the roller 1 I too far downwardly into its slot l8 when the segment roller I9 is not in contacting engagement or relationship with the roller l I. The feed rollers l2 and 20 position the circular on a supporting surface 30 which may comprise a continuation of the plate 8.- v

A conveyor 3| moves to the right, Fig; 1, and is adapted to receive the circulars 32 as they are being discharged by the feed; rollers l2 and 20;

i The conveyor 3| is adapted to move continuously at a predetermined speed and comprises a plurality of spaced pockets or buckets 33. The feeding speed of the circular is such that it will be properly positioned and received in one of the buckets 33 when the bucket reaches a predetermined position, V

Inasmuch as the conveyor 3| is constantly moving, it is desirable and necessary that the circular be fed properly with respect'to; the bucket and at the proper speed so that the circular will be received and positioned in its proper respective bucket, while the. conveyor is moving and without mutilation in any wayof the circular. In order to accomplish this arrangemenhthe feed mechanism l must be so constructed and arranged that the circulars will. be fed longitudinally. and transversely proportionately with respect to the movement of the conveyor- Therefore, the rollers ll, l2, l9. and 20 must be. arranged at the proper angular position to feed the circular in its proper pocket and continuethisfeeding during the move mentof the conveyor. Thelongitudinal speed of the. circular should be such that it is equal to the speed of the conveyor which is in a longitudinal direction. By this arrangement the. circular is always immediately opposite its corresponding pocket on; the conveyor and in a parallel position with respect tothe pocket whilemoving into it. Toarrive at the angularposition, of the feed mechanism Ill the velocity of the pocket and the velocity of the. circular must, be taken into consideration and this is shown diagrammatically in Fig, 6 wherein the bottom line 34 represents the velocity of the conveyor, while the line 35 indicates the velocity of the circular. The line 34 indicates the distance the conveyor travels in a given space of time, while the line 35 designates the. distance the circular has to travel in the same given length of-time. Therefore, Where the line 35' intersects a line vertical to the line 34 the general diagonal axis of-- travel of the circular corresponds with the line 35, and the axis of the feeding mechanism Ill comprising the rollers ll, l2 l9 and 2,0, mustbe at right angles to thisline 35; The axisof the rollers H, l2, l9 and 20 1's designated by the numeral 36, Fig. 6. Due to the angular position of the feed rollers ll, l2, l9 and 20, the circular 32 will be fed diagonally the proper distance at right angles to the bucket plus the distance the bucket moves. In other words, the longitudinal movement of the circular is equal to the longitudinal movement of the conveyor, and'therefore the circular moves longitudinally at. exactly the same speed as the conveyor. Therefore, when the bucket is in the position shown in full lines in Fig. and the circular is also in the position shown in full lines in Fig. 5, the continued movement of the circular in a longitudinal direction and the continued movement of the conveyor in a longitudinal direction I or mechanism. The relationship of the circular with respect to the bucket is at right angles tothe bucket and is exactly the-same as if the bucket were stationary and the circular were fed thereihto at right angles.

It is desirable that the circular being fed into its respective pocket be fed underneath an article which is carried by the pocket as the circular is to be enclosed in a package containing the article to be packaged. Therefore, in order tocause the circular to be, fed underneath the article, means are provided tocause the article tobe slightly raised as the circular is being fed-into the bucket. This means is more clearly shown inFig-s. 7 and 8 and comprises a plate 4.0 which is adjacent; the conveyor at the; edge thereof where the circular enters. This plate 4.0, has: a portion- 4I thereof raised above the horizontal line of travel of the circular with its ends inclined to form: 02.111.81.11": faces 42 there being a slot. or opening 43 provided therein through which. the circular passes as itis being fed into its respective bucket 33. Therefore, during movement of the conveyor the article designated generally by the numeral 44 will engage a cam surface 42 and be held in that position. until-j after the circular is; fed into the; bucket and underneath the article. Then, after the circular has been fed imposition the article will be caused to assume its original. position asit leaves the othergcamway 42.

The circular folding and feeding mechanism. is so timed with respect to the conveying. mechanism that; one: circular will be discharged, for every bucket as it moves to position.

In Figs. 9-- and l0- the circular 32 is fed between spaced driven rollers 50' and 5|: where theywill be fed bystraight movement" to and between. the diagonally-positionedrollers 52,:and 53. The roll.- ers 52 and 53 are in all respects exactlyathesame as; the; rollers 12 and-.2 0 The rollers 52, and. 53 include the same mechanism and driving elementsas the saidjrollers; l2 and 20.

In Figs. 11 and: 12, the; feed rollers 5!! and. 5|: are arrangeddn. proper feeding relationship with respect to the feeding mechanism I 0, therefore supplanting the previously described feeding mechanism designated by the numerals 2 to"! inclusive.

The invention therefore provides means for verse to themovable conveyor and at the same;

time longitudinally with. the movement of the conveyor. However, the feedisin a relatively straight line, the circular being fed constantly from the time it is arranged in feeding position until it is arranged in the conveyor pocket.

The invention also contemplates means for raising the article during the time the'feeding of the circular takes place so that the circular may be properly inserted underneath the article to be wrapped.
